The Rev Mike Huck would often say "This is not a dress rehearsal." We only get one shot at this life, but we also need to keep in mind the big picture. The bible says we're only passing through on our way to an eternal destination - the choice we make about the claims of Jesus determines what happens next. The original gospel blues pioneers often sang about journeys, especially on trains. This song is in that tradition.
lyrics
Like a river keeps on flowing
Something deep inside me wants to roam. x2
I don't know how long I'll be here,
But I know this world is not my home.
Like a stranger in a strange land
Nothing here's familiar anymore. x2
I've got things I want to do here,
But I know this world is not my home.
There's a train bound for Glory,
Leave your bags behind and get on board. x2
Let's enjoy it while we're riding,
But don't forget this world is not our home.
